[ANTRAX <antrax.bt () gmail com>]

Hi all, I'm ANTRAX from Argentina, and I'm owner of www.underc0de.org
Today, I going to shared with you about XSS in blogger. This is a very
simple, but isn´t fix yet..
This bug could be exploited by bloggers without administrator permissons.

Steps to reproduce the XSS:

1.- Create a new post in the blog and insert some script

2.- When the administrator enter in the administration panel in "templates"
section, blogger automatically executed the script, because blogger have a
mini-preview in "Ahora en el blog", then execute the script

3.- Ready! the script has been executed!
